FASTENING DEVICE FOR DOORS.

To all whom it may concern:

Be it known that I, LoUIs A. DAY, a citizen of the United States, residing in the clty and county of Philadelphia, State of Pennsylvania, have invented a new and useful Fastening Device for Doors, of which the following is a specification.

This invention relates to securing devices for doors, windows or the like and has for an object to provide a simple portable looking device for the use of travelers, tourists, etc, in hotels and other like dwellings and by means of which a door, window or transom may be securely locked.

The device is more particularly designed for application to doors or windows which are not provided with bolts, lugs or other fastening means, but it will be understood that it is equally adaptable for use as an auxiliary or additional look when the door is already fitted with looking devices.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention I have shown in the accompanying drawing one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a perspective of a device embodying my invention in its preferred form. Fig. 2 represents a detail section of a door showing my novel device in operative position. Fig. 3 represents a section on line a:w, Fig. 2. Fig. 4 represents a detail section of a window showing the device applied thereto. Fig. 5 represents a perspective of a modified form of the device. Fig. 6 represents a plan of the same.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings: 1 designates the body portion of my novel locking device, the same as here shown, being provided with a slot 2 preferably longitudinally disposed and of sufiicient length to carry out the functions of cooperating parts, later to be described. One end of the body portion 1 Specification of Letters Patent.

terminates in a head 3, pivotally secured thereto in any well known manner, while the opposite end carries a hook or anchor 4, preferably formed by bending a portion of the material of the body 1 at a suitable angle. The so formed anchor 4: is adapted to be either driven into the wood of a door jamb or window sash, or else may be inserted in the usual keeper for the door lock.

5 designates a cross-head slidingly mounted in the slot 2 and preferably substantially H-shaped to form side wings 6, which give an effective bearing surface to engage the side of the member to which the device is attached. This cross-head 5 is slidingly mounted in order to provide for the adjustment of the locking device, which adjust ment is made necessary by the varying thickness of doors, windows or the like. After the cross-head 5 is correctly adjusted, necessary means must be provided to prevent dis placement thereof and for this purpose I preferably provide one face of the body portion 1 with a rack 7 with which a pawl S engages. The pawl 8 is preferably pivoted to the cross-head 5, in the present instance being secured upon a pin 9 mounted in ears 10 formed integral with the said cross-head.

l1 designates a spring, preferably mounted in a recess 12 of the cross head 5 and secured at one end to the pawl 8, whereby the latter is normally pressed into engagement with the rack 7.

Referring to Fig. 2, the operation of the device will be clear, since in this figure 13 designates the swinging edge of the door and 14: the door jamb, having therein the usual keeper 15. Within this keeper 15 the hook or anchor 4c of the locking device is inserted and the door closed to the position shown in Fig. 2. The pawl 8 is now withdrawn from engagement with its rack 7 and the crosshead moved into contact with the door and jamb, at which time the pawl is closed and securely locks the parts in the position indicated and further, it will be apparent that movement of the door is positively prevented.

In Fig. 4 the device is shown as applied to a window and its attachment will be apparent, it being noted that the hook 4 in this instance, is forced into the wood by the cooperation of the sashes 16.

In Figs. 5 and 6 I have shown a modified form of the device, wherein the body portion 1 is provided at one end thereof with a head 3 having a suitable opening 17 with which a rod 18 has threaded engagement and contacts at the end with the cross-head 5. A knurled nut 19 is secured to the rod 18 in order to operate the same readily. This body portion 1 terminates at the end opposite the end 3 in a plurality of prongs 20 forming an anchoring means therefor, the same being adapted to be driven into the wood of the door or window to which it may be attached.

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable in the statement of the in vention and the above description and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1; In a device of the character stated, a body portion having a slot therein, a cross head slidingly mounted in said slot and having guiding wings on each side thereof ex tending above and below said slot, a flat side face on said cross head adapted to abut a door and door jamb when said head is in operative position, a rack on a side of said body portion, a spring-pressed pawl pivotally mounted on said cross head and adapted to rock in a line at right angles to the line of movement of said cross head and normally engaging said rack to form a lock, and a hook on said body portion for engagement with the keeper of a door lock.

2. In a device of the character stated, a body portion having a slot therein, a cross head 5 movably mounted in said slot and having guiding wings 6 on each side thereof extending above and below said slot, a side face on said cross head being adapted to abut against a door and door jamb when said head is in operative position, a rack 7 on a side or said body portion, ears on said cross head, a pawl 8 pivotally mounted in said ears and adapted to rock in a line at right angles to the line of movement of said cross head, the free end of said pawl normally engaging said rack to form a lock, a finger piece on said pawl, a recess 12 in said cross head, a spring 11 having one end seated in said recess and its other end in contact with said finger piece, and a hook 1 on said body portion for engagement with the keeper of a door look.
